人生副脑

Life Co-Brain (人生副脑) is an AI personal-knowledge tool that turns your thoughts, inspirations, emotions, and life experiences into a structured cognitive archive that aids self-knowledge and deeper decision-making. Instead of a generic note app, it organizes input into Memory Cards and Persona Cards, capturing not just facts but the personality and patterns behind them. A Daily Record feature prompts ongoing entries, while a Calibration step refines the model of you over time so the system reflects your evolving values and priorities. You interact with the archive through Brain Chat, asking your accumulated self questions and getting context-aware responses grounded in what you have logged. Additional modules include a Data Source Manager for connecting external information, Persona testing with history tracking, and Knowledge Cards for retaining what you learn. The product positions itself as a personal 'second brain' that becomes more useful the more you feed it, rather than a productivity tool aimed at task lists. It is account-based, with registration and login, and centers on individual self-reflection and long-term decision support rather than team collaboration. The interface is originally in Chinese.

Best for individuals who want a private AI second brain to reflect on personal experiences and support long-term self-knowledge and decisions.
